The first 3DS game to have the Irem logo will be Pachipara 3D, a new entry in the pachinko franchise that has also appeared on PS2, PS3 and PSP.

That's PSP's Pachipara Portable shown above. Screens of the 3DS version have not been released. Details are also going to have to wait, although Irem describes the game's genre as "Pachinko + Communication," suggesting that there could be some sort of wireless functionality.
